▎ 摘　　要

NOVELTY - Device compirises through-hole copper or through-hole silver or through-hole copper graphene or through-hole silver graphene or graphene made into hollow cylinder, through the through-hole copper or through-hole silver or through-hole copper graphene or through-hole silver graphene or graphene hollow cylinder hole in gas or liquid hits the hollow cylinder hole to inactivate and be torn by the hollow cylinder hole. The hollow cylinder is filled with through-hole copper or through-hole silver or through-hole copper graphene or through-hole silver graphene or graphene to kill virus tablets, adjacent through-hole copper or through-hole silver or through-hole copper graphene or through-hole silver graphene or graphene kill virus tablets are combined to kill virus cavity. USE - The device is useful for killing viruses and germs in gas or liquid. ADVANTAGE - The device: has excellent inactivation effect on new coronavirus, H1N1 virus and Escherichia coli virus, where, stainless steel with copper content of 20% can inactivate 99.75% and 99.99% of new coronavirus on its surface within 3-6 hours respectively; stainless steel with copper content of 10% can also inactivate 90% and 99% of the new coronavirus within 6-12 hours respectively; is capable of effectively killing the virus and bacteria in the gas or liquid with high safety; and kills the new coronavirus in the air and reduces the spread of the new coronavirus. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device.
